Get Ready for Rubies!

For those born in July, the ruby—the king of precious stones—is your birthstone.

Ruby is the red variety of the mineral corundum, colored by the element chromium. All other colors of gem-quality corundum are called sapphire, which means color is key for this royal stone.

The chromium that gives ruby its red color also causes fluorescence, which makes rubies glow like a fire from within. Paradoxically, chromium is also what makes this gem scarce because it can cause cracks and fissures. Few rubies actually grow large enough to crystallize into fine quality gems, and these can bring even higher prices than diamonds.

Accordingly, the name “ruby” comes from rubeus, the Latin word for red. In ancient Sanskrit, ruby translated to ratnaraj, which meant “king of precious stones.” These fiery gems have been treasured throughout history for their vitality.

Tough and durable, ruby measures 9 on the Mohs scale. Diamond is the only natural gemstone harder than ruby. Ruby’s strength and red fluorescence make it valuable for applications beyond jewelry. Both natural and synthetic rubies are used in watchmaking, medical instruments and lasers.

Due to its deep red color, ruby has long been associated with the life force and vitality of blood. It is believed to amplify energy, heighten awareness, promote courage and bring success in wealth, love and battle. Many cultures regard the ruby as a symbol of love and passion, and have long been considered the perfect wedding gem.

Rubies make wonderful gifts for a July baby, or anyone marking an important milestone, like a 15th or 40th wedding anniversary. If you’re in search of rubies as a gift or to add to your jewelry wardrobe, visit our Find a Jeweler search for an AGS credentialed jeweler near you.
